I find it mystifying that a 98-atom compound could take that long to open.  Does it have a lot of fused ring systems in it?  The next time it happens could you try this experiment:  close the molecule, set the "New Molecules" smart-display preference to "false", and open it again.  Any faster, or the same?

Dear chimera users/developers,
I have been experiencing an increase in the time it takes for chimera to open a molecular file, sometimes more than a minute for a 98-atom compound. This happens both with the windows [alpha version 1.5 build 29803] and linux [version 1.4.1 build 30192] versions. Typically, I'll restart chimera, but it soon slows down once more.
Any suggestions will be appreciated.
Thanks,
Austin-
