Re: Crossover Office 2.1

I had the problem that Photoshop would hang during an install.  Coping the 
cxoffice, .cxoffice and .loki directories from a working system resulted in 
the message from cxmaptest that  low 16Mb area is not free (got 
0x4001c000).  I was running with exec-shield supposedly disabled.

The solution I found was to disable the cron job that runs prelink and run 
prelink with -au.  Now Photoshop runs cleanly and all I have to do is find 
out how to keep the first 16M out of prelinks hands.
