SDL problem

I am using SDL/GL, for a 3d map editor, for my game. Everything works fine, however, whenever I use Windows''s file Open/Save dialogue box, I loose one mouse click. That means, after I select the file, and press Ok (or even if I press Cancel), the next mouse button click is lost, so I have to press the mouse button TWICE, to get an effect. That is annoying, because after you open a file (a 3d object), that object is attached to the mouse (you can move it around), and, if you right click the mouse, it should lace it at the current cursor pos. But, you always have to press the mouse twice, in that case, and that sucks... Another problem is that, after I use that Load/Save dialogue, and I click on the close/resize/minimize buttons, in the corner of the window, they don''t work. That onyl happens on Win98 SE, on WinXP it works fine... Any ideas? Thanks in advance. Height Map Editor
