Did the access denied problem come back *after* slick crashed? If so, perhaps the crash cause the access denied problem because slick died with vslick.sta or a tag file open. For the record, on my system (WinXP), it's not all that uncommon for me to get errors from Windows explorer like "can't delete file because it's in use by another program" which I can't explain. Does rebooting get rid of the access denied problem (I don't think it works for me). WinXP is very lacking in providing information on "access denied" errors or how to resolve them. Can you open and save vslick.sta in Notepad (with slick not running)?. Can you delete vslick.sta with slick not running.
Reports of slick crashing are fairly rare but I'm not sure how many people debug Vis Studio apps from vslick.
Maybe you could try to isolate the cause of the debug crash. If Windows thinks 'C:\Documents and Settings\emerkel\My Documents\My SlickEdit Config\11.0.2\vslick.sta' is in use, you could try to overcome this by using a different config folder. You can use the -sc switch when you invoke slick -sc somefoldername. If somefoldername is empty, slick willl create a new config there. With slick open, use help ->about to check what the current config folder is. If that gets rid of the access denied problem, maybe you could try to debug a minimal VStudio app and see if you can get a reproducible scenario of when it crashes. (Which OS do you use?)
You could also check and load the hotfixes on the support page of the main slick website, just in case.
Last but not least - if you've spent a while configuring slick already, backup your config folder first. It's possible to transfer the existing config to a new config folder at a later time once you've solved the other problems.
