I've reported this bug to Xara, but I just wanted to give you a heads-up...

If you group objects and apply a bevel, an error message pops up saying that beveled objects cannot be ungrouped and to ungroup, you must remove the bevel.

However, this error message keeps popping up after everything else you do in XX5 until you remove the bevel. There's no other way I could find to stop the error message.

This problem doesn't occur on Soft Groups, so you can use bevels on them as a workaround.

I also tested this in XX4 Pro and I didn't get the error message.
