Issue:

There are no spare stack pages. It may be necessary to increase the setting of 'MinSPs' in System.ini to prevent possible stack faults. There are currently <nnn> SPs allocated. 

Cause:

1. Edit the system.ini file by clicking Start / Run and typing sysedit and press enter. 
2. Open the system.ini Window.
3. Locate the [386Enh] section in the system.ini.
4. Below the [386Enh] add the below line.
   
   MinSPs=4
   
5. Once successfully added Click File and Exit. When asked to save click Yes.
