Last week some updates where released by Adobe on the following products:

• Adobe Flash CS4 Professional
• Adobe Flash Media Server

All of them are updates containing bug fixes and performance improvements. Adobe Flash CS4 Professional 10.0.2 Hotfix targets the Mac Pro desktops, Adobe Flash Player 10 Security Release Update for Flash CS4 Professional do fix this security issues and regarding the Flash Media Server 3.5 update read more in this pdf. Read also this post from Kevin Towes.

The last week I have been working on a Flash/Actionscript 3 project and everything worked well. The project got in an 75% finalized. Meanwhile I needed to install a software product and it crashed my Windows Vista. Saved the important data and tried to fix it without having to reinstall the whole OS and all my needed applications but no success. The inevitable has occurred – must reinstall the OS.

After re-installation I returned to my Flash/Actionscript 3 project. At a point in my development needed to delete an mp3 file but deleted the wrong one. So I wanted to add it back to the project’s library but I had a big surprise – an error occurred:

One or more files were not imported because there were problems reading them.

It was the same file that I added to the project before the windows’ crash but this time could not add it to the library. Tried all kinds of ways to add it but no success. Tried to modify its bit-rate also without success.

Started googling about the problem and found this on Adobe’s site:

Flash does not internally support MP3 files with a bitrate over 160kbps. Importing sound files over this size will cause Macromedia Flash to ask Quicktime to handle the import via Quicktime’s audio subsystem.

Although Adobe is saying that if the mp3 having a bit-rate lower than 160kbps will not be affected by this I can say that I tried to lower the bit-rate to that file and than import it in the library but didn’t work. It seems that the problem is not the bit-rate only.

Truly I didn’t reinstalled the Apple Quicktime after the crash (but had it installed before the crash). So out of my curiosity and because I wanted to get over this issue as faster as possible I installed Quicktime. And the import worked like a charm.

It seems that Flash authoring tool is – in a small measure – dependent on the system codecs.

So if you get into this problem install Quicktime and you should not have the problem anymore. If you already have Quicktime installed Adobe’s advice is to uninstall it and install the latest version by downloading it from quicktime.com.

Wish you won’t get this error.

If your Flash CS4 crashes when you try to edit some text object is because there is a problem with the font – it may be corrupted or may contain ambiguous data or there are more than one font with the same name or the font symbol name is identical to the Postscript name of the underlying font, etc.

The crash looks like this…

This can be easily fixed by going to adobe.com/support/flash/downloads.html and download the 10.0.2 Flash CS4 Professional Update.

Numerous bug fixes and improvements were added with this update. Some of them are listed bellow.

• Performance issues when dragging objects on stage, scrubbing the timeline, entering symbol edit mode in large AS 2.0 and AS 3.0 files.
• Performance issues when opening large files or files with many nested symbols.
• Performance issues when working in the library such as scrolling, selecting items in the library, dragging item to stage, editing symbol from library.
• Crash when selecting text field on stage with many fonts on user’s system.
• Text Property Inspector is stuck and some controls on the PI are not drawn with certain fonts on user’s system.
• Crash when creating a text object on stage when there are corrupted fonts.

Hope this will help you improving your Flex CS4 Professional experience.
