javaButton cannot to be clicked in QTP 9.2

[Maverick]

Hello all,

I have the following problem with javaButton in QTP9.2 :
In the test we have a code like

Code:

javaWindow("window").javaButton("button").Click

and it give an error

"The parameter is incorrect"

And the interesting thing - the button is in OR and can be found and highlghted, that's OK.

We have uninstalled old versions of JRE and installed new one "jre 1.6.11".
During several hours it worked but later stopped again...

Has anybody seen such issue/problem?

Thank you in advance.
