2003-09-01 Kristoffer Erlandsson
|
||
|
|
Fixed a bug where the week didn't update if we used %q style week numbering.
|
||
|
|
|
||
|
|
2003-06-28 Kristoffer Erlandsson
|
||
|
|
Fixed a bug where a mouse click caused an infinite loop
|
||
|
|
|
||
|
|
2003-06-26 Kristoffer Erlandsson
|
||
|
|
Fixed bug when longer strings didn't get cleared when shorter ones where
|
||
|
|
painted. Now only repaint the strings when they have changed.
|
||
|
|
|
||
|
|
2003-06-24 Kristoffer Erlandsson
|
||
|
|
