I'm not exactly sure how to further narrow this problem down, but I use RDTabs extensively in the office at work without issues. When I bring my laptop home and VPN in from work, it crashes almost every time, after perhaps 20 minutes of use. Has anyone else seen this, or have suggestions for further troubleshooting?

What error are you getting? Did you send an error report? (Admittedly, I haven't checked the error reports in a while.)

Admittedly I haven't noted the error nor have I submitted the error report. By habit I hit cancel on those. I actually thought they all go to Microsoft. Next time it happens I'll be a better error reporter. Sorry I have few details at this time.

RD Tabs catches all unhandled exceptions and emails them to me. It's opt-in and you get a dialog about it, but it looks significantly different from the Microsoft one. I did that on purpose for that very reason. :-)

EDIT: I should note that if you get the Microsoft one, I can't see those because I don't subscribe to their error reporting service (costs lots of money). But that only happens in rare instances and usually as a result of some external factor, such as Microsfot's RDP control completely barfing and causing some sort of DEP error or something.
