If you attempt to select Z80 protocol decoder then you fail to configure it. The mapping table between Z80 signals and LA channels is too long. Only the first 28 channels fit on the screen and there is no way to scroll down to the bottom. Suggest that either a scroll bar is added to popup box for setting mapping or split it into multiple columns. This is on a Lenovo Yoga 3 14", 1920 x 1080 screen.
Get a similar problem when trying to use Z80 decoder on Android Tablet. Bush Spira B3 10" Android 7 Build NRD90M Display 1920x1200 This time it only shows 1st 12 entries in the popup box without any means of scrolling down. libsigrokdecode 0.6.0-git-cb67584/4:0:0 PulseView 0.5.0-git-5620539
Agreed, we need a few more scrollbars in various places. This happens with various PV popups. Already reported as #183, marking this as duplicate. *** This bug has been marked as a duplicate of bug 183 ***
