In the last version of our software we changed the icon used everywhere in the application. This because the corporate identity changed and the old green icon needed to change to the new red icon.
What I did to change it:
- Use the new icon in the Application settings of the startup project.
- Use the new icon on all the forms (only changed 1 form because all others inherit from this one).
Everything works perfect accept for Windows XP in Best Performance mode (right click Computer, Properties, Advanced, Presentation settings).
When starting the application it shows the Login screen in the taskbar with the old icon which changes in the new icon within a split second. Of course; the slower the machine, the longer the old icon is visible.
Seems to me it has something to do with caching of the old icon.
Does anyone know why this is happening or how to fix it?
