Just to be clear: Are the regex filters case-sensitive?

[RonMarz]

For example, would a filter for the expression "wma" also work on "WMA" and "wMa?"

[DThor]

Yup, which means they're not case sensitive. Easy enough to check. You'll note the moment you hit "find", all search fields go to uppercase anyway.

I'm not sure if the standard Perl regex case escape characters(\u \l) work in v4 - I know they don't in the latest v5.

I upgraded the regex library recently. I believe \s is working now. I haven't tested the other ones.
