For years I was accustomed to Xojo’s complain that pictures were missing.
Today I forgot to copy the picture files in an HiDPI aware project, and yet, the project ran without a peep. I just tested more thoroughly : it appears that Xojo somehow makes a copy of the pictures, so once an image set is created, it is content without the original picture files.
Nice, is it not ?
In non HiDPI mode, nothing has changed and Xojo moans when it cannot find the original files.
