I have an app. it has several forms, views, queries and reports. In one of the forms i have 25 command buttons, when click any one, the app run one report (normally, a view with selection options). In my machine all works great. In client machines, when they select print preview and then close the view, my main menu don't work, only using ctrl alt delete keys. Sometime i receive a message: ...error in vfp500.dll the system will be shutdown ... but sometimes app continues working fine. In the client machines I installed the aplication and vfp500.dll, with no results, then the machines were formatted and reinstaled win95, everything was fine, until we installed iShare on the machine. Is there a problem with VFP and Ishare? There is some DLL that could cause this problem, maybe a newer version ?? PLS help.. i have been with this for more than a week.. regards,
