FindWindow to find several windows

Guys,
In MUI I have a Welcome page followed by a license page. I need to change the background of an additional text I added to the Welcome page. To that extent I

FindWindow $WELCOMEDIALOGHANDLER "#32770" "" $HWNDPARENT
GetDlgItem $CONTROLHANDLER $WELCOMEDIALOGHANDLER 1205
SetCtlColors $CONTROLHANDLER "" "${MUI_BGCOLOR}"

in onShowWelcome.

Works fine. However if a go to the next page (License) and come back to the Welcome screen, the DlgItem has again a gray background. The problem is that FindWindow finds a dialog corresponding to the license screen instead of the one on the Welcome page.
I checked with MS Spy++ and there are two Dialogs. The one I'm looking for and the one corresponding to the License page.

I can't seem to be able to find the one from the Welcome page. Calling FindWindow several times always returs the same handle...

Any help appreciated...

Try
GetDlgItem $CONTROLHANDLER $MUI_HWND 1205
SetCtlColors $CONTROLHANDLER "" "${MUI_BGCOLOR}"

Thanks! Works fine!
For the record, is it possible to iterate through elements with FindWindow?

No. You'd need to use C/C++'s EnumWindows or EnumChildWindows with callback functions. This is probably possible with the System plugin but I'm not that good at using it. I find it easier to write a small plugin to do the job.
