marker position bug (solved in 1.5.4)

[linkz]

To reproduce:
zoom in WF to show markers
click on one
change frequency manually from input box
markers are showing at same position

mousewheel zoom-in + zoom-out or a WF drag will replace them to their good position in the spectrum
NB: clicking button zoom-in or zoom-out is not replacing the markers

Will be fixed in the coming 1.5.4
