After experiencing a large number of blocked pop ups, I noticed the following.

1) The symbols on the 3 buttons in the upper right corner of each window (representing minimize, maximize/restore and close) had changed, and each symbol was replaced with an odd text character. The change affected appearance, and not funtion.

2) The arrow symbols on all menus changed, and each symbol was replaced with an odd text character. The change affected appearance, and not function.

3) The arrow symbols on all text boxes and check boxes changed, and each symbol was replaced with an odd text character. The change affected appearance, and not function.

I could not find any facility in Windows to change or revert these symbols. I looked into Windows Setup, the System Restore facility, and in the Control Panel's Display, and Appearance settings, and there is no applicable fix or adjustment. Obviously, this condition is not normal, but thus far, it has not affected the operation of my computer or any applications. However, the changes are at times somewhat confusing, and a return to a "normal" display appearance is most desirable.

Thank you very much,

Gooday
