A tree view list box has a large number of elements. The list_box read is returning a negative index that results in an error 41 when used with list_box find to look at elements above and below the current index. The item property doesn't error with the negative value, but accessing the itemtext$ property afterwards reslults in an error 11.
I coudn't find any index limits in the language reference, but it seems to be limited to something in the 32k range. Has anyone run into this and found a workaround? Is it a PxPlus or windows limit?
