[Bug-XBoard] RFE and bug question

[Raphael Clifford]

Hi,

I am using xboard 4.2.7 and would like to make a feature request for a 
way to edit the clock at runtime. This seems like an important feature 
which is currently missing.

Secondly, when I retract many moves in a game, xboard sometimes gets 
into a state where it claims any move I try to make is illegal. Is this 
a known bug? If not, how can I pin it down to make the bug report useful?

Cheers,
Raphael
