Hi Wally, I also had this tiling problem. We think it may be something about X11 in Mac OS 10.5 (possibly just 10.5.4), as the problem has not been observed with 10.4/X11. Two workarounds that were successful in my case (I don't know if they will fix all instances of the problem): (A) simply show the Command Line before saving the image. I tried hiding it again after that, but then the problem reoccurred, albeit in a more subtle fashion. (B) save the session, restore it in the aqua version of Chimera (still on Mac OS 10.5.4 but not using X11) and save the image. Yeah, (A) is easier, but I didn't discover that one until this morning, after receiving your mail. I hope these solutions are general! Sorry about the inconvenience, Elaine ----- Elaine C.
