Hi Thorsten . I have seen that when i start the slideshow from any slide it works for that slide . Navigating to the other slide during slideshow is failing .
What is the flow in following cases : a) When u press F5 on the current sllide Versus b) When u press Page Down on the current slide which is fullscreen Do the flows at a) and b) differ . Please point me to relevant code in the slideshow. Does the spriteHelprer update screen creates data of the consecutive slides for both cases (a) and (b) . If the flows differ , it would mean that my VCL code fails for the other case. Note that when i navigate the presentation in non-slideshow mode , it works . Do you see any obvious problem , which i am missing . Any pointers from you will help me debug the issue with my bitmap / virtual device code. Regards, Karl.
