I'm not a database developer myself, so I will have to test it to see what is happening. It will possibly take a few days, as I'm in the middle of moving to another town (and finally going full-time into ViEmu and text editor development), and I'm not sure I will be able to install a DB server in my laptop and without the MSDN CDs.
As long as it's a regular text editor inside VS, there may be a problem with intercepting the window but it shouldn't be too difficult to fix. If it's a completely different text editing system, it's a completely different issue.
I'll get back to you as soon as I gather more information.
