RE: Window Manager Performance...

["Dawson, David W" <david dot w dot dawson at lmco dot com>]

Well, I also used the lesstif mwm for a while and noticed (using the MS Task
Manager) that mwm was consuming an *extraordinary* amount of the CPU.  

When I first used lesstif, I compiled it all myself, and had no such
problems. That, however, was several versions of lesstif ago, and being the
lazy soul that I am, I now use the precompiled binaries.

I don't know if this is related to the manner in which the latest binaries
have been created, or if it is related to code changes in the version
upgrades.  I never pursued this, having moved on since to IceWM.

Good hunting....
