What steps will reproduce the problem?
1. Complete an achievement.

What is the expected output? What do you see instead?
Expected: the screenshot to show both the chat log output of the achievement as well as the brief Blizzard "visual" of the achievement (which occurs by default at the bottom center of the UI).

Instead: the screenshot provided by MementoMori fails to record the Blizzard "visual". The screenshot seems to record things too late.

What version of the product are you using?
r39

Do you have an error log of what happened?
No errors.

Please provide any additional information below.
After that failure, I manually changed line 62 in MementoMori.lua from "self:ScheduleEvent("MementoMoriAchievment", 2, Screenshot)" to "self:ScheduleEvent("MementoMoriAchievment", 1.25, Screenshot)". As that is the default time used in the Multishot mod (http://www.wowinterface.com/downloads/info9590-MultishotScreenshot.html) and that mod records the Blizzard "visual" of achievements just fine.

Did not work. A further achievement "visual" was not recorded after the line change. No problems with boss-kill screenshots, however.
