I have a weird problem with the command-ended event of an editor-reactor. When just one drawing file is open, everythingh runs smooth and fine. But when another drawing is opened, the command-ended reactor function sometimes causes AutoCAd to crash. This behavior is not reproducable - one and the same drawing at one time can cause the crash, and at another time will open just as it is expected to do.

I modified the reactor function so that it does nothing when the calling command is "OPEN", but this made no difference.

No I found that when I let the reactor function (print "OK") there is no crash at all. Funny that (print 'OK) is no help :-)

Instead (print "OK") I can also have the reactor function create an entity (line or something else) and entdel it immediately again, and this also prevents AutoCAD from crashing on OPEN.

Does anybody have an idea what's going on here?

TIA
