Mission Lightposts malfunctioning.

I've got several issues with the mission light posts. Sometimes, I'll be going through a mission and the next lightpost just doesn't show up. I click the next button, and the next page loads, but I don't get the yellow lightpost popup after the page loads.No matter how many times I go back and forth between the pages it doesn't show up. This makes some missions undoable. My next issue is, although I'm not sure if something can be done about it, is that lightposts hide behind flash. For websites made mostly of flash this makes completing them difficult, if not nigh impossible. The third issue, its more of an annoyance really, is that lightpost popups follow the webpage's css coding. This gets annoying when the webpage uses white text. White text on a yellow background is very hard to read. I usually just click the next button, because the text is next to impossible to read.
