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.
