Allastair : >> Following Razzak's indication that the buttons on a form only work with BMP images - contrary to all the documentation - I amended the form that seemed to be giving me the most problems. <<
I never used JPG buttons, but all the forms with which I had problem do uses several BMP buttons (this remark is to look for the 'common denominator'). >> Repeat for the other 4 buttons but the third one crashed R:Base when I clicked on open. << I had in the past to change my BMP buttons, and I remember having similar problem. I had to delete the 'old' buttons, save and exit the form, and then re-enter the form and add the 'new' buttons. >> .... Start R:Base with the app - still crashes. Put the pause back in then give up and go to the pub - it's Sunday. << In your case : - the form crash EVERY time you use it (you can duplicate the problem), - PAUSE FOR 2 before ENTER/EDIT USING fix the problem. Is this correct ? What OS are you using ? J.M. GRATIAS, Logimatique
