I use the right mouse button to select a vertical block of text, and then type to write a vertical comment, for instance. I use this feature extensively. Sometimes, the editor will drop the selection before I am done typing. For instance, I may want to comment out a block of code with "// FIXME". I will get the "//" in, but then the vertical selection is dropped and I end up writing FIXME to the last line in the selection. The previous version I used never had any issues with column editing.
Any idea what is going on, or is this a known issue?
