I have a question that I can't solve... I have tried so many things and I have so many suspects but I can't solve this...

I post a pic to ilustrate the problem, If you see it... you will notice a difference between the two displayed names... the blank space without background and the blank space with a white background... One screenshot is from my desktop pc (the first one without the white) and the other is from my laptop (the second one with the white)...

If you see it detailed... you can watch that is only a background problem cause the font in white is equal in both...

My desktop is pentium D 3.2 GHz with windows xp pro sp2 in spanish and my laptop is a AMD Semprom 1.6 Ghz with windows xp home sp2 in english... both have ATI video cards enabled... and so on... (if you need more info ask me)...

I can figure out why this difence in the way that display names are displayed... I have tried many many things and nothing solves it... I don't know if that is MP!L bug or incompatibility with some software that I have installed in my desktop pc or anyother thing...

By the way I have all last releases of WLM, MP!L, SP and MD installed in both...
