Can you post a file to look at? There will be a slight freeze when the TLF property inspector appears (since there are a lot of settings), but 10 seconds sounds abnormal.
It already happens whenever I place a textfield on stage and set its type to "TLF Text". No matter what action I perform with flash (menu, tool, timeline clicks) everything is really slow and flash freezes for several seconds when there is a TLF textfield instance on stage. Most of the time when clicking something the window title bar of flash changes its look to a window which seems to have crashed (see screenshot).
I saved a fla with one TLF Text on stage; please find it here:
Please let me know when you grabbed the file so I can delete it.
Actually the problem does not occur anymore; I dont know why this is now not gonna happen again but I can now work with TLF without problems
your problem solved by remove you unused font from your system. when you have more font installed on your system make this problem in flash.
