I have written an application which I use to measure equipment status overnight.
When I am using the application during the day, all is well. However, sometimes when I return in the morning, the application seems to have changed the resolution in windows to some extent.
My dialog application is the same size but, the selection down-arrows on my combo boxes change to a number 6, my combo boxes do not work correctly.
When I minimise my application and look in Windows Explorer, the resolution and size of fonts have changed.
When I close my application and reopen it, all is well again.
Can anyone advise what the problem might be?
