How to activate various callout styles?

Hi,

I have downloaded evaluation versions of Technical Suite X5 as well as X6 from Corel's website and face the following problem in both versions (both are 32 bit).

Please help in resolving this issue with the callouts: 

  • While drawing callouts, the shape menu is not visible. I have reset the workspace several time and played with all possible options before writing on this forum. Actually, the menu did appear once but subsequently disappeared. While the menu was visible it was great to have text boxes at the end of the callout that automatically adopted to the size of the text.  
    How to I activate the callout shapes option? I have included a screenshot of the menu from the pdf manual for your reference.

Many thanks in advance!

Regards,
