安裝了aptana後，代碼提示彈出框顏色不匹配，會出現白底白字的情況，根本看不清。解決方案如下
The issue is that Aptana uses the system tooltip color for their code assist boxes.
In the default theme on Ubuntu 10.04 this results in white on white.
For Ubuntu 10.04, go to System>Preferences>Appearance
In the Appearance Preferences window select Theme, then click the
Customize button.
Select the Colors tab, and then click on Tooltips text color to
change it.
Choose something that contrasts well against both the tooltip background (black) and the tooltip text (white.)
