In the next release there is going to be a reduction of the GDI count, but we have discovered another reason for the high GDI object count. The reason has to do with all of your detached charts have their own control bar and some of those control bar items use graphics rather than text and each of those graphics is a separate bitmap object. If you disable the control bars on the detached charts and find you have a significantly reduced GDI count and then improved performance, then this really proves just how totally and completely abysmal and poorly designed the Windows operating system is in regards to GDI objects. This is beyond comprehension that having a significant number of bitmaps allocated is causing such a problem. It should cause zero performance impact. There really is no other way to say this than the Microsoft engineers who worked on this are complete dummies. And the fact that they have not even taken care of this to this day is shocking. Please do let us know if removing the control bars from detached charts improves performance significantly. If so we will then add this to our list of items which can cause high CPU usage. And it is the buttons which use graphics which is the problem. If a Control Bar button is just plaintext it is not a problem.
