I'm having an issue with Studio 2015 freeezing to death after Ctrl-E-ing a string from Xbench. This happens on a small subset of Studio projects, but it always happen in those, where it happens.
I understand this is a very broad report. Please advise what information I can give to help you narrow it down.
I'm up-to-date version of Studio 2015 and XBench's plugin.
