More of the same issues with my PC today, none of my graphics software wanted to load up until well over half an hour after booting and loading windows. Not so much as a splash screen! Paint.net did load but as before, it seemed to freeze when I clicked or moused over “acquire” in order to get at the scan dialogue. I have no clue why rebooting would help since it’d been previously powered down, which is essentially the same as only working every other boot. Confused yet?
The only thing that worked was the standalone HP scanning software. Then Photoshop loaded!
