I see the same behavior here, as soon as the cursor is on the chart the desktop icons start constantly refreshing. It doesn't do it on my laptop though. Dan

Hi inventor1949 and eDanny,
I just responded to an email regarding this specific issue, but allow me to clarify the issue here as well.
The reason we are seeing the flickering is due to performance demands. In inventor1949's case it has to do with the fact that there is not a specific performance section related to graphics, and so the graphics use general CPU resources, and it causes a spike as you move the cursor which causes the flickering.
This would be why you may see it on some PCs but not on others, or during only market hours when the volume is higher. To resolve you will want to reduce the performance requests by referring to the Performance Tips.

With Crosshairs selected, my desktop icons flash when my cursor is hovering over that chart. With a total of 19 charts and DOM's open, I cannot understand why this would be a resource issue. Seriously, what is the difference in load from Crosshairs On to Crosshairs Off?
Has to be a bug.
I am running a dual core with a couple gigs of RAM and there is no resource issue other than this one.
I saw a post suggesting the fix was to go into Add/Remove Programs>Ninja7>Change>Repair but that was aimed at he same problem for NT 6.5 and I have not seen anyone try this in NT7.
Dunno but I would like to use the crosshairs.

Hi shortski and inventor1949,
Since we focused earlier on the workspaces there are some Nvidia cards that show similar issues with .NET, and so you can update your video drivers, and then also check the hardware acceleration on the graphics card and reduce that speed.

Updated and reduced speed all the way down. The only difference is the Crosshairs flash now instead of the icons.

Ryan, I can send you everything but the wsp. The Indicators are almost all propriety and I doubt you will have any of them.

Hi Shortski,
I will follow-up based on that information, and the indicators should not affect the workspace as I mostly concerned with knowing the overall configuration.
