Quite frequently I get reports of users unable share Powerpoint slideshows via clearsea. The reason for this is because powerpoint starts a second application once a slideshow is started. This causes the content to disappear since clearsea is still trying to share powerpoint in slide preview mode. The only work around for this is to alt-tab back to the clearsea sharing window and re-select the "power point slide show" as the shared application. Allowing PC users to just share their full desktops like Mac users can would eliminate the issue.
