Thank you for your post.
This is the correct place to report issues for FileMaker Go. Or, you could have also used the forum board "Report an issue".
Our Development and Testing department are already aware of this issue. That is, executing Scroll Window [Home/End] does not bring you to the first/last record in table/list view. No other information is available at this time. Until this is changed, use the workarounds you have discovered. I have attached your post to the original report.
After fiddling around I got this workaround;
Go to Record/Request/Page [No dialog; 2]
Go to Record/Request/Page [First]
Scroll Window [To Selection]
hopefully they will fix this soon, but at least you can get the same functionality using this.
