- Sub: More problems with TrackMouse?
-
- Helllllllp:
-
- We have been getting some mysterious problems lately with ß9, and reading over
- some past links, there seems to be a pattern. I hope that Apple can comment
- and lead us to salvation.
-
- On Aug 30, CDA0220 posted a link that reported a bug in TApplication.TrackMouse
- dealing with crashes due to improper handling of grafPorts. The error occurs
- during debug writelns. We got similar crashes and, applying the suggested fix
- in the memo, the problem went away.
-
- Then, on Sept 8, D0420 reported crashes while working with dragger-type
- commands. Again, the link is suggesting that the crash is somehow linked with
- debug writelns, and the stack crawl points the the CommitLastCommand, and the
- subsequent Free call. Well, again we are experiencing similar crashes, most
- often resulting in system error 25.
-
- In our case, while we are not working with TrackMouse as D0420 is doing, we are
- getting the crash in CommitLastCommand but only (and here's where it is a
- little weird) when the CommitLastCommand is caused by a mouse action. To
- elaborate a little, we have a menu item that causes a TCommand to be created
- and which can be committed in a variety of ways; if the commit is caused by a
- keyboard equivalent to another menu command then everything appears to work
- well, but if the mouse is used for a menu command, then booooom.
-
- I haven't been able to track it all the way down, but when I _can_ do a stack
- crawl, CommitLastCommand and debug writelns are in the fray.
-
- Are all these problems symptomatic of some larger problem, that the fix by
- CDA0220 didn't quite address?
-
- What is Apple's response to the fix by CDA0220??
-
- Lastly, as more and more of these problems and fixes to ß9 are posted, will
- Apple somehow collate them and provide "Official Patches to MacApp 2.0ß9", or
- some such thing???
-
- Hoping someone can help,
