In latest version 5 (187) this still happen too.
I press STRG+F type search string in box. Its very very rare, but its happen
that its jump partly random in file. Thats not a joke. ;)
EDIT:
I can reproduce it. test text:
texta textb textc textd texte texta textb textc textd texte texta textb
textc textd texte
texta textb textc textd texte texta textb textc textd texte
texta textb textc textd texte texta textb textc textd texte
texta textb textc textd texte texta textb textc textd texte texta textb textc
textd texte
1. I have a text in clipboard for replace search-text
2. STRG+F
3. type texta in dialog and start search
3. "texta" is selected and with STRG+V(SHIFT+INSERT) i replace "texta" with
"textX" (from clipboard)
4. press F3 for search next "texta" for replacing
5 after few F3 and replacing text its jump to end of text and beginning next F3
from top of the text.
Maybe this helps?
