I try to use transitions made by Software, but they won't preview or even work when I'm presenting the slideshow.
I tried most of the transitions made by Software and they still haven't worked! Only Powerpoint compatible and Additional transitions work.
I hope someone can help me on this!
Please try the following:
Open File | Options, switch to the System tab.
Here, you have to set "Enable OpenGL animations and transitions". If this option is disabled, the Softmaker transitions are not working.
When this solution doesn't help, maybe your graphics driver is too old/not compatible. It must be at least 3.2
And also please note: Some of these SoftMaker effects can be saved only in SoftMaker Office Presentations files, and not in Powerpoint files.
