I'm using Flash builder 4.6 (and have used prior versions of flash builder as well) with a flex/actionscript project on a Windows 7, 64 bit box. Flash Builder itself (not the launched application) is horribly slow and unresponsive. I do not have the auto build turned on or design mode on
Here are some of the problems I regularly have:
- Opening the window, if it has been minimized, and clicking anywhere on it causes the window to be greyed out and have the "(not responding)" message added to its title bar. It starts working after 15 seconds.
- Using the arrow keys to move up and down in a .as or .mxml file is jerky. I.e., some keystrokes move at the rate I hit them, but others pause, wait a few seconds, and then move. This also occurs with mouse actions.
- Using code navigation like F3 or <CTRL>-<SHIFT>-G causes Flash Builder to pause while it thinks. In the case of <CTRL>-<SHIFT>-G, it pauses so long that one thinks there are no references (because the search starts with 0 results).
- Building code within flash builder takes minutes. Even the modification of a single file takes forever.
In general, I've found working with Flash Builder one of the worst development experiences (I've worked with Eclipse for the last 6 years, VIM, & Visual Studio too) I've had.
