Dopesheet runs out of frames :(

Hello! I have been creating an animated short, but have come across a problem with the Dope Sheet Editor. Past the 1000 frames mark, the slider bar thing at the bottom begins to shorten/go off screen, so i cant animate past there easily. :frowning:

Is this an error on my part, or is the interface glitched? Hereโ€™s a video i made to demonstrate the problem a bit better. :slight_smile:

System Specks โ€˜nโ€™ stuff :smiley:
Windows 7 64bit
Blender 2.65 32bit(64 bit runs really slow :frowning: )
8gbs of ram
3.8ghz, Intel I7 processor
not sure what else might be needed :smiley:

Thanks in advance!

try either mouse wheel up and down to zoom, OR
middle mouse left and right, to pan โ€ฆ

keep in mind the dopesheet editors scrollbar has 2 circles in each end, if you click and drag these it changes the โ€œvisible rangeโ€

Middle mouse works, but it snaps back to where it is when i do it again :(. Thanks though, i tried some random key combinations and holding down ctrl and mousewheel pans the way i want it to, thanks! :smiley:

Edit:
For anyone who has the same problem, heres the soloution if found in a more clearer way :smiley:
One way to do it is hold MiddleMouse, then drag :slight_smile:
Another way to do it is hold down Ctrl and then scroll :slight_smile:
