Here's another oddity which I don't remember in previous versions. This is Win7 RC 64bit, and UltraEdit 15, now updated to 15.10, I did a completely fresh install on a new PC I built when the Win7 RC came out. I did not import any customizations or preferences, I re-created everything from scratch.
I had no problems and everything works fine and I love some of the changes. My toolbars are pretty customized, as are my wordfiles, but other than that it's a pretty standard installation. Preferences are in AppData rather than registry; I accepted most of the installation defaults (I may have declined r-click explorer integration on 15.00 but allowed it on 15.10). UE is the default handler for txt, log, ini, all those file types in the left column of the splash screen.
Here's the oddity. If I double-click an associated file in an Explorer window with UE running, it loads into UE immediately, as I would expect; HOWEVER there's also about 5 or more seconds of cursor hourglass anywhere on the screen except within the UE window. This hourglass does not affect my ability to work on the newly loaded file immediately, even while that hourglass keeps spinning outside the UE window.
If I run task manager to look for clues, I see that a SECOND PROCESS of UltraEdit starts up when I double-click the text file in explorer, even while the file opens in the instance of UE that was already running. After a few seconds, this second process of UE disappears, as does the hourglass cursor. I do NOT have 'allow multiple instances' enabled in preferences.
If I DRAG a file from an explorer window ONTO the UltraEdit window, as opposed to double-clicking it in explorer, none of this second-process or hourglass stuff happens. Ditto if I load a file from within UE using the open dialog box--no hourglass. Only double-clicking in Explorer causes it.
Finally, I also get 5 seconds worth of hourglass pointer some of the time (but not all the time) when I exit the program altogether. In other words, the UltraEdit window closes, I can do anything I want, but there's an hourglass pointer spinning for a number of seconds after the program has visibly closed -- again, it doesn't interfere with doing other things. So far I have not been able to observe anything in task manager that correlates with it.
The computer I was using when I made the original post in this thread is now backup-only, but it also got a fresh install of Win7 RC 64-bit, and I tried all this on that one, too. Same exact behavior: hourglass if you double-click a file to open it, no hourglass if you drag a file onto the UE window. And same hourglass some of the time when you exit the program. Happens on 15.00 or 15.10, both builds, both computers.
I call these oddities because they don't rise to the level of 'problems' and because I haven't seen anything similar in previous versions of UE or Windows. I don't think this happened with UltraEdit 14 on Win7 64-bit beta 7000 (but I don't guarantee my memory on that one). Prior to this I've always used 32-bit Windows. I'm just curious if anyone has a good explanation.
