It has been several months that I fully migrated to Linux. The whole company has moved 100% to Linux, all servers, desktop ... every machine. The only traces of Windows are in two of my personal laptops, the IBM ThinkPad with Windows 2000 and the Compaq Presario with Windows XP, which I have kept for testing purposes only. My top 5 regrets after migrating to Linux are:

An Ext JS, a beautiful Javascript Library, ComboBox on a Toolbar fails to display when the browser window is resized or there is another div with 100% width. The problem is most likely related to resizing of the Toolbar which causes the ComboBox to stop displaying.
