[Wine] wine config

[yoma819]

i have just done something really stupid!
while messing around with the config settings after having problems emulating steam i saw a bar titled resolution i think
i set it to the largest value
now every time i run wine config it is such a big window i cannot move it down to correct the error
do i have to reinstall or is there a config file i can edit from the command line?
