I've been living with it and really didn't expect you to acknowledge any issues and to point to other apps that is status quo when reporting problems to any vendor about any app. So first thing I do is trouble shoot, then isolate so it really is the ONLY SW (in this case context menu) item running (other then requireed MS OS related) . And FYI COMODO is my "suite" but it's all disabled for this exercise.
Again it doesnÃ”Ã‡Ã–t ALWAYS happen (this is not a RMB issue RMB items works as advertised on MP3 and other audio file types) . It only when folders, and a few other file types, are present in the highlight tree. SO MAYBE if you ever DID have strange behavior you may have simply shrugged it off and attributed "issues" to MS or other apps.
To reconstruct - this is just one way Example (one of many):
Environment: windows Classic view (classic start menu and all files visible - I do not hide system files, or folders, or extensions)
Now Right click on My Computer; Now left click "Explore"; Now left click on Local Disk C (this expands out the folder and make sures it is actually selected/highlighted so we dont' have any empty arguments being paseed):
NOW go up to the menu bar at top and left click "Edit" (like maybe you wanted acess to the "Select All" option it provides) If you don't get a debug crash for "m2wshlex.dll" then your right I'm the only one with this issue (of course this app is the only context item other then the OS running so??) .
A web search indicates a few others, not just me, with issues . Searching on "w2wshslex" yields a couple and the first one is goes back to 2004
I'd be happy to send you a debug/crash dump? For now I'll just disable it since I know what is causing MY problem. I'll simply turn it back on when I need it. Unless a patch becomes available (but since you run it on 5 Win XP SP 3 machines it must be the user)
