Currently I am testing FoxIT to be utilzed for consistant long periods of times. An abnormally large portion of the folks I am testing this with are subject to seizure disorder from quickly falshing objects.

FoxIT is an astoundingly good program. However, it does have one flaw I have identified that I do not see mention of anywhere else. It has a fairly significant blink effect when a PDF file is opened. IT is extremly noticable inside an internet browser such as Internet Explorer. While most other aspects of this program are wonderful, this aspect would keep me from allowing most of the folks Im testing with to use it.

I am not a programer so I am not sure how to refer to this. We see it quite a bit in my company. Our developers even have to rework our internal applications to keep this from occuring.

Is this a consideration the developers here would be interested in tackling? If so would have to wait for a future release or would it be something significant enough to warrant some effort in BETA2?

If I found a high quality way to capture it on video would you like to see it?

You are right.
With my system the short blicking stopped when I set the video acceleration to none.
Ever tried this?

Mario,

I tried to reproduce your results this morning and was not sucesful. I turned the video acceleration on a couple desktops to NONE. The results were the same. Did you take any special steps once you turned off the accelerated graphics?

The way to notice is the most is to open mixed content in a webbrowser. By mised content i mean, a web page that might have static HTML at the top of the page and a viewport at the bottom for the PDF to be viewed.

I will take a screen shot and PM it to you.

No I did not.
But maybe it was suggestion...
It's going so fast.

Can you give some more info of the computer you are working with?
refresh rate of monitor?
Internal memory?
Video memory?
number of colours tht are displayed?
Branch of graphics card?

Do you see the same blinking with other programs like AR?
