Page Preview in Calc

I use Windows 7, Home Premium OS. My version of LO is 4.2.6 using English as the language. I have loaded 24 sheets in Calc and the page preview no longer functions. If I remove three sheets the page review functions as it should. I have never had this problem before when using LO version 4.1.6. Is Calc limited to a maximum number of sheets? This does not happen while previewing very large Writer files with many images. Thanks for any help.

Please take a look to this thread:
