the funny thing about it is that its ONLY the xcgal module which causes that problem. any other works well. so i really think it has to do with xcgal. but why? there must be something which sets any margin smaller than it should be for the maintheme :-/

please help me :/

If you mean that xgal is making the left hand margin smaller (this happened to me with the "easy" theme coincidently also has a clock script) open your themes style sheet and look for something similar to this:

/* Main Table Columns */
#main {
width: 100%;
}

#leftColumn {
width: 12%;
vertical-align: top;
padding-right: 1px;


and adjust the width of the left column maybe by only a couple of percent or pixels, another thing I found was by playing around with blocks some of them will force the margin wider without having to play around with the style sheet.
Hope this helps.
