Klemens,
 
 your screenshot shows the execution-point of your application while
 being debugged. It looks like you accidently hit the F9 key which
 has started the debugger.
 
 You can verify this by checking if the title bar of VX shows something like:
 
 project - Visual Xbase++ - [test.exe/test.prg][1:IDLE]
 
 the IDLE or RUNNING token in the titlebar documents the
 state of the debugger. If not debugger is active only the
 PRG source currently edited is inserted rightmost of the
 titlebar.
 
 If for some reason your screenshot was taken with definitive
 no debugger active - the the execution-point should not
 visible at all.
 
 regards

Hi
sometimes within my code I find a line blue marked and at the left side in the column showing the line numbers is a strange yellow sign - look at the picture below:
 
 
Can anyone please tell me what this is. Why is the line blue? It seems not to be a break point, but what than?
