LO 4.2 Base crashing on MBPro Retina OS X10.9 JRE 7

I recently installed LO 4.2 on my MacBook Pro 13 Retina and try to use Base database application. When adding a formatted field or a special mask to a formatted field LO stop responding. I am running OSX 10.9 Mavericks with Oracle JRE 7. Does any one knows how to solve this issue?

‘…When adding a formatted field or a special mask to a formatted field LO stop responding…’
Would you kindly give more details about this - for example, are you trying to add a formatted text box to a FORM? You also appear to be successfully using Base with Java JRE 7 - do you also have the Apple version of Java 6 installed - see HERE.

Do you also have Java 6 installed on OSX? Check in your LO preferenced under advanced that LO is actaully using Java 7 by default. Maybe that’s causing the problem.
