Async messages

[mea405]

In VAST under Windows XP there is observed the following effect:
if one takes a scrollbar with the mouse and moves it and
if one seizes a capture of a window with the mouse or changes the size of a window
then async messages stop to be processed.

Maxim:

Could you clarify what you mean by "seize a capture of a window?"

Do asynch messages stop being processed permanently, or to they continue after the scrolling or window resizing is completed?

Could you clarify what you mean by "seize a capture of a window?"

I mean "seize the title bar of window". It is usually done for moving window.

Do asynch messages stop being processed permanently, or to they continue after the scrolling or window resizing is completed?

If async message queue will not be overflow, processing of messages continues.

You can see this effect on a simple example. I understand that it not asynchronous messages but the same effect.
Exec script in workspace

[
|t|
t := Time millisecondsToRun:[
1 to: 20 do: [:i| (Delay forMilliseconds: 100) wait. ]].
Transcript cr; show: t printString; cr
] fork.

And then try to move during execution of this script some seconds a window.
