I discovered the folowing about my previous problems.
1. The datepicker only shows 1 time => this happens in IE9 but not in Firefox. Seems to be in issue in IE i don't have other browsers yet so maybe you can give it a try as well.
2. The yearRange does not show again when selecting the min year => it seems it is caused because i use yearRange: "-100 : +0", however i actually want to show a range from the current year - 100 years back. I know i can just write 1911 : 2011 but then i have to change it every year.
What should i use instead of +0 to show untill the current year.
I want to show the yearRange like above and set the minDate and maxDate to force no entry before 100 years from now backwards and not after the current date.
Again it will be for a birthdate entry.
Thanks and please inform me if the first problem is only on my IE or really an IE problem.
