Steps to Reproduce Behavior
---------------------------

WARNING: Attempting the following steps may adversely impact some 32-bit
applications and necessitate uninstalling then re-installing any affected
applications. Specifically, attempting the following steps with Visual FoxPro
5.0x on a Windows NT 4.0 machine results in an abnormal start up of Visual
FoxPro 5.0x after the Temp variable in the User Variables list has been reset to
a solitary directory. To correct this problem, click Start, Run, and enter
"C:\Program Files\Devstudio\Vfp\Vfp.exe" -A at the prompt. Visual FoxPro 5.0x
may then be started normally from the Start Menu or from a shortcut. However, if
this method fails, it is necessary to uninstall and re-install Visual FoxPro
5.0x.

1. In Windows NT 4.0, open Control Panel and double-click the System icon to
   open the System Properties dialog box. Click the Environment tab.

2. Select the Temp variable in the User Variables list. In the Value text box,
   add a second folder to the Value of the Temp variable. Here is an example:

   If the variable's value is: %SystemDrive%\TEMP

   Change it to: %SystemDrive%\TEMP;%SystemDrive%\Tmp

   The second folder can be any name.

3. Press the Apply button and then click OK to close the dialog box.

4. Start Visual FoxPro 3.0x or 5.0x. One of the behaviors described in the
   SYMPTOMS section occurs.

5. Quit Visual FoxPro 3.0 or 5.0x.
