Hi all.


I'm in the process of moving from a 10.7.5 iMac to a brand new iMac with 10.8.3.  Using a Time Machine backup.


I installed Java Version 7 Update 21 from Oracle (same as had been installed on the "old" iMac.  How come it didn't come over to the new Mac in the backup??? Hmmm...)  (I know!  I know!  it's because I didn't restore system info, just user profile...)


Tried launching an app that uses Java and it launched and ran fine.


Tried launching TD Ameritrade's Thinkorswim app, which I use extensively every trading day and it gives me a weird msg:

My understanding (Oracle web site) is that you can't have both Java 6 and 7 installed at the same time.


However, Oracle also says that Java 6 is dangerous and that it's preferable to install Java 7...


So...  What should be the next step???
