I'm using Blender 2.53 beta 2.53.0 r30581 on a Amd Sempron 3100 machine with 2gb of RAM, an ATI Radeon 9250 graphic card and windows xp pro SP3 operating system.

I tried to use the 'repeat last' function (by pushing the button on the button shelf on the left side of the screen) after a simple face extrude, even with the default cube, but it only works along the Z axis. If I extrude along the Z and click 'repeat last' it works like it's supposed to, but if I extrude along the X or the Y axis, then click 'repeat last' it doesn't work so well (seems that in one case the extrusion is repeated wit a zero length, and in the other case the extrusion is repeated inwards).

Here the steps to repeat the bug:
- with the default scene loaded, TAB to edit mode
- switch to select face mode
- select the face in the X direction
- E to extrude along the X axis
- on the left tool shelf click REPEAT LAST.

Same thing happens if you choose the face in the Y direction.
In the Z direction it seems to work fine.

Thanks in advance for your kind attention
Best Regards
