issue happens after pressing 'continue' button. opens new window. next system.out.println("continue button clicked") not displayed in console until close window manually. please help.

ps: please pardon coding style, try.

this old topic please verify iedriverserver version, old versions had problems when managing modal dialog windows (some problems fixed version 2.38, please refer changelog). help, having similar problem , updating version solved issue.
