Had a strange problem on two PCs I have just upgraded to 4.91 SP2 plus
patch kit c.
When I go to the 'advanced' option at the initial login screnn and type
in the 'username' box the characters appear right to left rather than
left to right:

ie: administrator is coming out as rotartsinimda

The standard username and password fields work fine.

Any thoughts?!?
I installed patch kit c by copying the files over the main 4.91 sp2
install files as suggested in documentation.
