This is the first time I've ever experienced this problem. I was typing along in TextMate and suddenly it started to get really sluggish, so I pulled up activity monitor and whenever I edit text in TextMate, it shoots up to 50 or 60% CPU usage. I have an Intel Core 2 Duo MBP running OSX 10.5.2 and TextMate Version 1.5.7 (1455). I usually leave TextMate open for days at a time and I've never had this problem before. I tried closing TextMate and reopening and that didn't do anything. Any ideas what might be causing that?
