file extension mask case sensitive

[CADE20]

When trying to open an .rdp file, the file extension has to be lower case. Higher case file extensions are being ignored.
This affects version 0.150.

This is not a bug, filenames are case sensitive. Do not expect GNU/Linux to be as borked as Windows is. Or are you trying to say something different?

[CADE20 (witshadow)]

I do not mean that for opening file names should be case insensitive. The file open dialog only shows .rdp files and not .RDP. Since rdp files are usually used for accessing a windows box it would be better to support showing .RDP files in the open dialog as well.

Ah, that's something different, yes... tsclient should perhaps be more UNIXy and do not even bother with extensions when listing files. They either parse or they don't. Will check on it.
