Just before I powered off my computer to come back home, I had troubles with a color set to a String (in g.DrawString of a Canvas).
After a Xojo quit,
Clear the Xojo Cache folder,
Power Off,
Power Cord remove during 1 minute (who knows ?)
Power On,
Run Xojo,
Load the project,
Run the project in the IDE.
NO CHANGE I THE PROJECT SINCE THE LAST COMPILE.
The application now displays the string using the correct color.
(the color was stored from a Property to disk / loaded from disk into a property).
My productivity today suffer from that.
