I have tried to alter mouse flags code to reflect what have we learned so far. Can you retest with current trunk please? (Maybe backup Switch.cpp so that we can do those LOGs again)

Hi Mirek,
I downloaded and compiled the latest nightly build (11829) and when I made a single touch over a Switch control and now the control works as expected.
Thank you for the fix!

Just for the records: I put in the source of with upp-11799 with following log line in Switch::MouseMove, Switch::LeftDown and SwitchLeftUp:

LOG("MouseMove");
DUMP(p);
DDUMP(keyflags & K_MOUSELEFT);


I modified also the GtkEvent.cpp modified as per you message.

With those modifications I get an error and the application does not start:

****************** PANIC: Invalid memory access!

/usr/bin/xmessage
Error: Can't open display:
Segmentation fault

P.S. I am sorry I am not able to provide you with a prompt feedback, but programming is just 10% of my job, so I often have to take care of other assignments.
