ShowModal Delphi and Win7



I am using SUMATRA in my project with Delphi 2007 and when opening a form with a panel with embedded sumatra, if this form has any call to another form and it is executed with Showmodal, it does not work. It is a problem in Windows 7, since in Windows 10 it works correctly. Can you help me? Thank you


This looks more like a Delphi issue (but I am not a programmer) and probably best raised with those that do know Delphi and Windows. On stack overflow here is a question that seems to be possibly similar to your issue but the answers appear to be conflicting to my untrained eye
