I may be mistaken (and here's where the collective mind comes in), but I was under the impression that, if AU3Info could read the title of a window, so could AutoIt. However, AutoIt seems NOT to be able to read the titles of SunAwtDialog windows, because, when I use WinWaitActive (or WinWaitNotActive) with SunAwtDialog window titles, my AutoIt scripts hang at that point. If I substitute a Sleep command for the WinWait... commands, the scripts work fine. Since WinWait... commands would make my scripts more reliable and stable (rather than being affected by system response time vagaries that could make timers unreliable), I really want to use that approach. The WinWait... commands work with other windows automated by the script, just not with SunAwtDialog windows.
