[GRASS5] a question about grass 5 tcltk interface

[Michael Barton]

Glynn,

While your explanation makes sense, it doesn't seem to exactly match 
what I am seeing--at least not obviously.

1. I open grass and a bunch of windows open up--saved window geometry 
from the last time I used grass.
2. I select the option to automatically resize all the windows, and 
they shrink to the correct initial size.
3. I save configuration and quit grass (I also check the save 
configuration box in the quick dialog)
4. I reopen grass and the same windows reopen, but all have grown about 
23 pixels in the y dimension. They grow down, not up. They do not grow 
in the x dimension. This only happens for menus & dialogs, not for 
monitor windows.
5. If I continue this without doing an automatic resize, they all grow 
another 23 pixels each time I reopen grass. They at least grow to the 
edges of the screen if I let them, and perhaps can grow off the screen. 
I can send you screen shots, but don't want to send something big to 
the list.

I can's say that my Mac WM is not somehow  resizing these windows, but 
somehow  the saved geometry is augmented by about 23 pixels downwards 
in the y-dimension only and for tcltk menus and dialogs only, every 
time I quit or open (I don't know which end this happens on). This 
seems odd.
