Welcome the Lightzone Project!

I revisited this and your previous post and am a little confused. When I mouse over the toolbar I am returned the text of what the tool is. I have to wait a couple of seconds before the text appears. Do you not see anything when you mouse over? As for another possible (programming ) solution , perhaps the same technique for enlarging/shrinking the histogram can be used. The 3 dots between the histogram and the toolbar can do that trick.

On my copy of LZ I can raise the memory to near 8 MB, even though my desktop has 16 MB available. When I go into HTOP, I see less then 4 MB of memory used with Firefox, Thunderbird, and LZ all running at the same time. I seems that the max limit selected is not a problem but YMMV.
