The following is merely a question and probably
should NOT affect any release date but before
submitting any kind of bug report I wanted to
get an idea if this is experienced by others:
Maxima 5.9.2 on Windows (XP)
TK XMaxima
Issue: while sitting IDLE this process runs
at (near) 100% interferring with other programs
being actively used.
Work-around: Use Task Manager to reduce process
priority base to "below normal". (Still runs near
100% but doesn't interfere much.)
Do others (on Windows) experience this with this
version?
BTW: I love this program; thanks to everyone who
works on it.
