I tryed to track down the issue. but i can't install JVCL with debug now...
anyway, trying to step into in the code, I found that after the time expires the
call of FOndraw in procedure TJvImageDrawThread.Draw (line 79 in JvImageDrawThread.pas) in some way call procedure EnterCriticalSection; external kernel32 name 'EnterCriticalSection' and never return...
  Sorry can't do more about it for now. :(

You MUST apply all updates for your Delphi version, we don't support non updated versions.
Please do so and try again.

I've installed delphi 7.1 update and database suplemental update. tested, same error.
  Uninstalled JCL+JVCL, installed again, but still same error, nothing changes :ยด(
  Must I install any other update? (must add that version 330 was used without any error and no need of updates)
  Also I've added a new issue, that occurrs in instalation (both, Delphi 7 or 7.1) and may be related...number 4957 -> [^]

Hi all,
  Issue 4957 is solved by changing path of the instalation of JVCL, but it din't help this issue. :o(
  So it is not related after all.
  it is realy simple to test, put a jvWaitingprogress on form, change it to active true and wait the time.... it will realy never stop, neither in designtime.

Eh!! That was good. I tried to reproduce and my IDE just hung up.. COOL!
Just put it to Active and wait when it reach the end, after that IDE just goes not responding.

Ah, that was the part that was missing: One MUST wait for the progress to reach its end to see the lockup.
