Xolox 1.3 seems to not like Proxomitron.

Crashes if I have the proxy enabled.

If I "bypass" xolox has no problem.

From the errors it looks like xolox's browser is having trouble with the javascript that proxomitron writes..

Maybe you should try some other proxy programs like A4Proxy or something else.... You could also disable the proxy when using Xolox... or use another program

the xolox browser component supports everything that IE suports.. It just wraps IE in another frame, all internals are the same.

IE does have numerous javascript errors with proxomitron..

would an IE error crash the program?

I'm using the 359 build now.

I have to say regardless, this xolox is pretty good.

it seems faster and more stable once its up and running...

Yes, IE errors do crash Xolox.

Can you say exactly at what page/URL it crashes?

I do not know all the errors' effects of Xolox. I know that none of the simple ones (404, 403, ect.) have any noticable effect execpt the usual page that IE brings up for that error instead of what you where trying to get. Some script errors do seem to crash Xolox (there were issues with that in the past). I'm sure anything that would crash IE would cause Xolox to be dragged down with it.
