Sublime Text 2 v2.0.1, build 2217
Windows 7 x64 Professional
If I switch to the 4 column layout from any other layout ST2 will crash, with the following exception:
If I'm already in a layout other than "Single", and I have one or more files in any of the other panes, then ST2 will not crash.
However, even if I successfully switch to 4 column mode using the exception listed above, if I then move all files back to the first pane, upon removing the last file from the other panes, ST2 will crash.
