ALT+TAB Six-Second Delay in Real/Standard Modes (59654)
The information in this article applies to:
- Microsoft Windows 3.0
- Microsoft Windows 3.0a
This article was previously published under Q59654 SYMPTOMS
If you are using a PS/2 Mouse Port style mouse, you may experience a
five- to six-second delay switching between MS-DOS applications in real
or standard mode in Microsoft Windows 3.0.
NOTE: This occurs not only on genuine PS/2 machines, but on any machine
with a PS/2-style mouse port, such as the COMPAQ 386S and 20e.
CAUSE
This delay is caused by the presence of an MS-DOS mouse driver. The MS-DOS
mouse driver reinitializes the mouse port with each ALT+TAB, thus causing
the delay.
WORKAROUND
If you can do without a mouse driver for your MS-DOS applications, this
increase task switching considerably on this type of machine.
