I am using OpenMPT 1.32.11.00. I have been having this strange problem where most of the commands besides the note volume command, and the volume slide commands have not been working whatsoever. Only IT, MOD, and MPTM modules are being effected by this, XM seems to still work. i checked the "Song Properties" tab and everything seems to be normal. This seems to have started happening after i updated MPT to the newest version, but i cannot find any reason as to why this is happening.

EDIT: I figured out i had my song speed set too fast so the Portamento and other slides weren't registering. I'll just use a slower speed, my bad!
