There is something wrong with my codes' showing.(as shown in my attchment)
In Visual prolog 7.4 & 7.5 PE, it is OK,
however,in VIP 7.1 & 7.3, codes are black blocks,which can't be read and edited.
I'm confused, could you tell me why and how to solve it?
P.S:My OS information------Windows 8.1 (64-bit)
Thanks in advance! :-)
