In variable definition, when you type a variable name, the suggestion list box appears. If accepting suggestions with any character not valid in a symbol is set, the suggestion is accepted after a character not valid in the symbol is entered, which is very annoying. The suggestion list box shouldn't appear when a variable name is typed in variable definition.
I am using VC++ 6.0 and VA_X build 1423. By the way, build 1418 doesn't have this problem.
