We HAD some problems a long time ago, but they were fixed. This is a
tricky object to handle in terms of IDL managing its lifecycle. If
you come up with a set of steps to reliably reproduce the problem, please
submit them to ITTVIS tech support, so we can look at it.

I'm using IDL 6.3 on a Windows machine. Now I can only get the problem
to happen sometimes, so I'll try to figure out what I do that causes
things to go bad. Are there any known problems with the default font
object?

What version of IDL are you using?
Here is my output log from 6.3:
IDL> otext = obj_new('idlgrtext', 'aaa')
IDL> xobjview, otext, tlb=tlb
Compiled module: XOBJVIEW.
Compiled module: UNIQ.
Compiled module: FILEPATH.
Compiled module: PATH_SEP.
Compiled module: IDENTITY.
Compiled module: IDLEXVIEWMANIP__DEFINE.
Compiled module: XMANAGER.
IDL> widget_control, tlb, /destroy
IDL> obj_destroy, otext
IDL> heap_gc, /verbose
I didn't see the problem in 5.6 or 6.0 either.
