Delphi 7 Win32 App display anomaly on Windows Vista
Posted on 2007-08-08
A perplexing issue has arisen with running one of my Delphi 7 Win 32 apps. on Windows Vista. I recently introduced a 'constrainedresize' event into 4 similarly constructed forms within that app. These event handlers simply contain MinHeight and MinWidth constraints so that the user cannot scrunch them up below their optimum designed display. One and only one of these forms displays with about 30 to 40 pixels of the bottom chopped off, the others are fine ! This window contains a page control (as do the others) and successively selecting the page tabs progressively causes more and more of the window to be truncated at the bottom ! This is pretty weird stuff given the similarity between the forms.
Does anyone have any ideas as to what might cause something like this (it's Vista specific)?
How one window can be affected but not similar windows ?
Ever seen anything like before ? cos I have no idea at all what may be going on here.
