I've recently encountered an unexpected behavior from tk_getOpenFile
which I have never seen before in my years of tcl'ing...
I'm running Tcl/Tk 8.4 on WinXP. Starting wish and issuing
tk_getOpenFile from the wish prompt brings up the usual dialog. As I
navigate the file browser, hovering with the mouse over any particular
file causes a little information box to appear for that file. I am
finding that when I hover over PDFs which were created using "Acrobat
Distiller 4.0 for Macintosh" (as determined by the file's Properties
window, under the PDF tab), the information box does not appear.
Instead, wish will usually (but not always) seg fault (i.e. I get seg
fault on the command line in the shell where I started wish; the proc
does not end with a catchable error). However, hovering with the
mouse over other PDFs (e.g. created with "Acrobat Distiller 6.0
(Windows)") or any other type of file works fine.
Trying this in the file browsers of other applications (e.g. Firefox),
which are presumably using the same MFC dialog, works fine. The PDFs
themselves open just fine in Acrobat Reader, and this is true for
multiple such PDFs.
Anyway, this seems like a strange, perhaps trivial situation, but is
unexpected and fairly reproducible. Has anyone else encountered this
problem?
There is a similar open bug on this, and I believe I tracked it down to an issue in one of Adobe's shell controls that borks more than just Tk:
