| You might try moving/deleting the .idl directory from your HOME.  For example, on windows this is: C:\users\mminari\.idl
 When you launch ENVI, it will be re-created 'fresh' and may clear up any configuration conflicts.
 In IDL, go to Window->Preferences->IDL->Graphics and switch to software rendering.  Then launch ENVI:
 IDL>e=envi(/debug)
 
 Try the process and see if your menu shows up as expected.
