Generally I don't expect people will have problems with DragThing by itself, but occasionally changes in the operating system or third party software can cause difficulties.
If DragThing suddenly stops working, or gives error messages, ask yourself if you recently changed anything. Did you upgrade to a new version of the Mac OS, or install a new piece of software? If so, there might be a connection.
It might be that there is a later version of the software available, or that it just doesn't work well under the version of the operating system you have.
If DragThing is crashing, the easiest way to find out what's causing the problem is to look at the crash report, which is generated whenever any application crashes.
On 10.2 you can switch on the crash logging feature in the Preferences window for the Console application (found in the Utilities folder). The crash report will open up in a separate window and you can copy it from there.
On 10.3 and later crash logging is switched on by default. When an application crashes a dialog will appear asking whether you want to submit a report to Apple. Click "Submit Report " and a window will open showing you the crash report in the bottom half. You can copy the report from here, but there probably isn't much point submitting DragThing crashes to Apple, so just close the window when you're done.
The crash report hopefully contains useful information about what happened. Send me any reports for DragThing and I'll see what I can find out.
One thing though - if you see any references in the crash report to "APEBundleMessage" or similar "_apeSomething" lines, it's most likely a "haxie" at work, especially if the crash occurs at login. Try disabling any haxies you have installed, and see if the crash goes away. If it does, it might be worth mailing the crash report to the authors of those utilities too.
If you do have any problems, please let me know at:
Another possible cause of problems is damage to your "DragThing Preferences" file. All your docks and settings information are stored in this file by default, and if it becomes damaged this can make DragThing behave in an unpredictable manner. If you have a backup, it might be worth trying it, otherwise you may need to remove the file and recreate your docks again.
And of course DragThing might just have a bug. Check on www.dragthing.com to see if it is a known problem, and if I have a newer release of DragThing available that fixes it.
But if you think you've found a problem I don't know about, please tell me. It's helpful if you tell me what version of the Mac OS you are running, as well as the text of any error messages you are seeing. If you see a crash, any crash reports are appreciated too.
