CAT not working with 2.5.3. Replacing hamlib to the latest has CAT working but no PTT on my IC-705.
2.5.2 and its hamlib file works for me but if I update hamlib to the latest, there's no PTT just like above. Reverted back and 2.5.2 is my latest stable release.

No such issue with either or earlier releases with my Windows 10 Lenovo and Asus laptops. Thankful for this amazing program.
