    Why would a program throw a "Run-time error '401' Can't show non-modal form when modal form is displayed." every time it starts up.

    Bad programming or mismatched application versus equipment or Windows version are among the reasons. Bad programming is the most likely.

    Program works OK on my laptop which has same Windows version so I can't see how it could be bad programming or version mismatch. Tried reinstalling and tried safe mode - both to no avail. The program in question is Skygolf's CaddieSync.

    Perhaps conflict with other running programs. Programming is still possible since good programming takes many variables into account and what is present on one system isn't necessarily present on another. Run time errors are generally always related to poor programming.

    Viral infection and memory issues can also be the cause. Sometimes it may run well if you create a pif and set the parameters it needs.

    Finally found the conflict was with McAfee SystemGuards. Turning this feature off permitted CaddieSync to function.
