I'm running TOS1.4. Something really strange happened last night...
Here's the sequence:
- under NeoDesk 2.05 I had two file widows open
- ran msh.prg (MWC)
- exited
- moved mouse to "NEODESK" (accessory dropdown) before the two file
windows were redrawn
- got the outline of the first window
- the dropdown appeared
- the 2nd window appeared
- the first window filled in, overwriting the dropdown with which it
overlapped
Things happened so fast that I don't recall any more details, but the file
window and dropdown were a little confused until I clicked the mouse (I
think this is where it ended). I was unable to reproduce it at will, but
if it happened once...?
Seems symptomatic of code which does not prevent interrupts (like mouse asking
for a dropdown) during a critical few instructions (like between drawing the
outline and filling it). Just a WAG (wild-assed guess), but....?
Ciao,
Pierre
