I am trying to adapt a PowerPoint presentation to Impress. In PowerPoint, slides have multiple lines of text, each appearing on click by the operator. Opening this .pptx file in Impress gives strange results for the transitions. Each slide is displayed with all the lines of text except the first already displayed. Clicking causes the first line to appear. The next click causes the first line to remain and all subsequent lines to be blanked for a moment, then they reappear. This continues with one click per line of text until a click as been registered for each line; the next click then displays the next slide. How do I get Impress to perform the same as PowerPoint?
The PowerPoint file I am trying to use is the last file listed at https://sites.google.com/site/kingaroywriters/home/brian-smith-workshop?pli=1
This file is a .pptx, edited under Impress, to replace local hyperlinks with web links to YouTube videos, then saved by Impress in .pptx format.
