Something I have noticed when working with Delphi 2006… at some point it stops being shown in taskbar… nice… IDE is still here, works and all but only way to go back to it is to use Alt+TAB.

Strangely enough if you minimize/maximize it once, everything starts to work again until next time…

I suspect that this is side effect of having Delphi 2007 on the same machine since it only started to happen after it has been installed and I have no problem with it working properly in my VCP session.

It is more of inconvenience, but just something to be aware of, I guess

Yes, this is caused by an issue in Delphi 2007 and occurs because BDS 2006 uses the newer runtime packages. More about this here:

I occasionally see this behaviour in Delphi 2005.

I only have Delphi 4 and 2005 on my machine.

I will try the minimise trick to get the taskbar button back. I hope it works, because it is annoying.

The minimize “trick” is very specific to a bug in Delphi 2007. FWIW, I’ve never heard of issues related to the IDE’s taskbar regarding Delphi 2005.

I would agree with Steve on D2005 issue… never saw anything like this for combination of D2005 and D4.

It happens to me very often in BDS2006 and I don’t have D2007.
Usually I notice it when it’s not focused and I want to go back to it, I look in the task bar and it’s gone! Alt-Tabbing finds it and upon refocusing, shows the icon again.
Minor annoyance (except the 1st time it happened and I tried restarting it thinking it was gone for good!)

It’s disappointing that the “trick” won’t work with BDS2005, but as I said: it’s only a minor inconvenience now and again.

This is a known bug. See

Ahah! It happened today so I got to test it. This is interesting.

I remembered the issue incorrectly. Rather than disappearing from the taskbar, BDS 2005 disappears from the ALT+TAB list!

I can consistently reproduce the problem. It happens when I open a property editor window in the IDE. The task bar button does not disappear (fortunately!), but BDS 2005 disappears from the ALT+TAB list making it impossible to switch back to it from the keyboard. I am forced to use the mouse to click on the taskbar button. 😐

Specifically I was working with the SQL property editor window of the tQuery component. Can anyone else reproduce this with BDS 2005?

One more crucial piece of information:
This only happens when the IDE is using floating windows. Using the (new) standard IDE layout does not exhibit the problem.
