I've begun experiencing 4-7 seconds second pauses when switching between files today. It happens every time I switch tabs after editing a file. I press ctrl-tab, the cursor changes to the hour glass, and I have to wait before I can get control back.
Since I made changes to my color scheme recently, I switched Komodo back to the Classic color scheme & checked the 'classic mode' checkbox to no effect.
Has anyone else experienced? I figure out I could try nuking all of my settings next to see if that would rule out a local setting.
