As a desktop and mobile developer, I've upgraded to CS5.5 as soon as it came out.
I loved the new features like the copy/paste layers, and all of the bitmap stuff (export/convert) which really saves me a lot of time during development.
(and I could finally use air 2.6 to create iOS apps directly from the IDE.)
BUT! I can't stand the constant memory errors (even a simple "convert to symbol" will get me an "insufficient memory" msg 1 out of 5 times...) and the random stupid crashes...
is it just me?
please try this example:
1. draw a simple rectangle on stage. select it and convert it to a movieclip (F8) [Symbol1].
2. draw a second rectangle next to the first one, again select it and convert it to a movieclip (F8) [Symbol2].
3. select both symbols (movieclips) and try to convert them to a single movieclip that contains both of them [symbol3].
on my rig - this will crash flash.
a simple "convert to movieclip"...
Not Just You . But it works for me.
