SUMMARY
When you choose to close the Winpopup service from within the Windows
version 3.0 or 3.1 interface, the following warning box appears:
This will STOP the message popup service.
This message is a bit misleading. Although Winpopup is stopped, the
message service and the Netpopup service are still fully functional.
If the machine receives a message in this state, unpredictable
behavior can result:
- The pop-up may not display correctly (it may be in 43-line mode,
40-column mode, or another undesirable format).
- Windows may hang when the pop-up clears.
- The screen colors may change when the pop-up clears.
- A blank Windows error box may appear when the pop-up clears. The
Window's focus will be completely directed at the OK button in this
error box. Choosing the OK button may clear the error box, but
Windows will hang, usually with multicolored vertical bars painted
across the screen.
Even when Windows hangs, the message service and Netpopup services
generally remain active. The machine is essentially hung--it will not
respond to either keyboard or mouse input. However, it will still
field messages and display them on the screen.
To work around this problem, don't unload Winpopup if Netpopup is
active.
