Hi,

In&nbsp;the&nbsp;latest&nbsp;development&nbsp;build&nbsp;I&nbsp;have&nbsp;noticed&nbsp;that&nbsp;panning&nbsp;a&nbsp;WMS&nbsp;layer&nbsp;is&nbsp;taking&nbsp;a&nbsp;very&nbsp;long&nbsp;time&nbsp;(minutes&nbsp;in&nbsp;some&nbsp;cases)&nbsp;and&nbsp;the&nbsp;network&nbsp;transfers&nbsp;almost&nbsp;30MB&nbsp;over&nbsp;this&nbsp;time.&nbsp;&nbsp;Zooming&nbsp;does&nbsp;not&nbsp;have&nbsp;any&nbsp;problems&nbsp;and&nbsp;takes&nbsp;less&nbsp;than&nbsp;a&nbsp;second&nbsp;with&nbsp;network&nbsp;traffic&nbsp;around&nbsp;600KB.

Development&nbsp;builds&nbsp;5.5.110&nbsp;and&nbsp;5.5.117&nbsp;have&nbsp;this&nbsp;issue.

Version&nbsp;4.0&nbsp;does&nbsp;not&nbsp;have&nbsp;this&nbsp;issue,&nbsp;takes&nbsp;only&nbsp;seconds&nbsp;to&nbsp;pan&nbsp;and&nbsp;transfers&nbsp;600KB&nbsp;network&nbsp;traffic.
