The size of the mouse pointer being used can also have an affect on graphics and also the presence of text. I use a larger mouse cursor found in the scheme called: "Windows inverted extra large system scheme" Sometimes when reading or editing text, Jaws will be unable to read text near the position of the mouse cursor. Usually refreshing the screen after moving the mouse out of the way will correct this situation. it is probably a good idea to keep the jaws cursor away from the focussed item. >>> Doug Lee <doug.lee@xxxxxxxxxxxxxxxx> 12:53 pm Thursday, January 28, 2010 >>> Off the top of my head, I have found the following all to have an impact on when and how reliably or consistently JAWS can detect a graphic and assign it a consistent CRC value: - Screen resolution (desktop area). - Color depth. - Video driver (maybe). - A screen refresh (Ins+Esc), which can make a graphic appear or disappear from the JAWS view. - How large the graphic is, in either dimension. - How close the graphic is to other color changes on screen. - Whether the mouse pointer is touching the graphic, as this can actually change some graphics. - How much impact the graphic's dimensions or position have on JAWS' concept of the character baseline for the line containing the graphic. That's enough variables to make me resist relying on graphic recognition whenever possible.

I've got a jawsVid.dll version here that shipped with jaws6.2, I forget what version number the jawsvid.dll is now, but you can see it in the second control Tab if you hit altEnter on these files, and I remember doing a really indepth report to fs once, about how when this particular jawsvid.dll file was loaded, jaws could see/identify stacks more graphics with the jaws cursor, than it could with another derevation/version of this jawsvid file. I don't know the total answer for you, as to what fs thinks about this, or how much it knows or cares, but I would totally encourage you to write to eric about this at, Edamery@xxxxxxxxxxxxxxxxxxxxx ericdfs and ask him? tell im the problem and why it is so irksome and unreliable for this to be the case, and ask for his thoughts. but, at least to give some modicum of comfort to know that your not going crazy, and your not alone in this experience, and it is very non-optimal and frustrating in my view too.

In my scratchLive application graphics sometimes disappear. If you do a screen refresh or if you click the graphic, then Jaws can see them again. And some graphics are never able to be seen by Jaws. I am now a beta tester for ScratchLive so I want to be able to tell them about this problem. Is this a jaws bug, or do you think it has to do with the way ScratchLive is written? > If it weren't for HSC, I would be in big trouble. > Thanks! > Gian Pedulla > GianniP46@xxxxxxxxxxxxx > > LETS!
