AbleCommerce Shopping Cart Software

I'm developing some personalisations using VS 2005. I can run the development version of AbleCommerce 7.0.2 on localhost through IE and change code through VS2005, but if I run the code within Visual Studio it loops trying to open the first page and won't start. This means I can't use the debugger!
I've tried reinstalling everything I can think of but still no luck.
Has anyone experienced a similar problem?
Any ideas what else to try?

Debugger in VS2005 is woefully difficult to troubleshoot. Could be a hundred different things. I found several things to try in Google just searching.

Eventually I just upgraded to VS2008 Pro - debugger works FAR more reliable now.

I agree with Joe - switched to VS2008 Pro about 8 months ago and life is easier.
I did run VS2005 with debugger against past versions of Able by attaching to a local IIS instance of the Able web site instead of trying to run on VS Webserver.exe - worked out fine. File -> Open -> Web Site -> Local IIS...
